This is smart inject and it was introduced in Cobalt Strike 3.14 for the product’s built-in fork&run post-exploitation features. See Malleable Command and Control for more information.Ĭopyright Help/Systems LLC and its group of companies.Īll trademarks and registered trademarks are the property of their respective owners. Cobalt Strike’s strategy to avoid this behavior is to pass key function pointers to its post-exploitation tools, when they’re known. This allows you to cloak Beacon activity to look like other malware or blend-in as legitimate traffic.

Redefine Beacon’s communication with Cobalt Strike’s malleable C2 language. Interactive communication happens in real-time.īeacon’s network indicators are malleable. Let's start by implementing a simple BOF that just. Beacon object files are just standard C files that allow for the execution of WinAPI functions as well as additional beacon functions defined in 'beacon.h'. Beacon will phone home, download its tasks, and go to sleep. Using this working sample code we can start to create an implementation using cobalt strike's beacon object files. Asynchronous communication is low and slow. You may also limit which hosts egress a network by controlling peer- to-peer Beacons over Windows named pipes and TCP sockets.īeacon is flexible and supports asynchronous and interactive communication. Use Beacon to egress a network over HTTP, HTTPS, or DNS. They allow adversaries to configure the C2 method used in an attack. LISTENERS Listeners are at the core of Cobalt Strike. We will also look at Cobalt Strike from the adversary’s perspective.

Cobalt Strike’s interactive post-exploit capabilities cover the full range of ATT&CK tactics, all executed within a single, integrated system. some of the core components of Cobalt Strike and then break down our analysis of these components and how we can protect against them. Beacon is Cobalt Strike’s payload to model advanced attackers. Cobalt Strike is a commercial, full-featured, remote access tool that bills itself as 'adversary simulation software designed to execute targeted attacks and emulate the post-exploitation actions of advanced threat actors'. Most commonly, you will configure listeners for Cobalt Strike’s Beacon payload.
